Application filed July 14,1905. Serial No. 269693. I

To @ZZ whom, t rtfty concern:

Be it known that i, Crans S. DEAN, a subject of the King of Great Britain, residing at Buffalo, county of Erie, and State of New Improvements in Rotary 'E@tors-@131.-uhh@L of which the following is a specification.

This invention relates to rotary motors or turbines. It has been proposed heretofore to operate tube or flue cleaners or Scrapers by compressed air, steam, or water and to direct the jet of motive yfluid against a turbine or vane wheel at an angle to the general plane of the wheel. This subjects the wheel to great sidewise pressure and causes the wheel and its abutting parts to quickly wear out;

My obJect is to provide in the present invention a turbine or vane wheel having its vanes arranged transversely ofthe wheel at right angles thereto and to dispose the ducts or ports conveying the motive fluid in such manner that they discharge in the same plane as that of the turbine-wheel, whereby the turbinetvheel is subjected to rotary action only and all end or side thrust entirely obviated, thus minimizing wear and obtaining the 'greatest rotative effect 'from the Huid-pres sure.

Another object is the provision of an improved shell' construction of few and simple parts, adapted for rapid and easy assembly and separatiomand which rovide the greatest ossible space for the fnd-pressure.

T e invention is set forth in detail hereinafter, and the novel features are recited in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of the invention shown within atube or iiue which is in section; Fig. 2, a longitudinal section, and Fig. 3, a cross-section on line 3 3 of Fig. 2.

'An ordinary tube or flue of asteamsboiler is shown at 1, and the present invention is intended to be inserted bodil within the flue or tube and fed therethroug 1 by hand.

The shell or casing consistsof a bach part 2, a iront part 3, and a central part 4, which latter is an annular band held between the parts 2 and 3 byv thel bolts 5, which connect parts 2 and 3 together. The air, steam, or water hose 6 is coupled to the back part 2 and conveys the motive iuid to `the device.

IThe back part 2 is hollow to permit the free passageof the motive iuid to the spaces 7, which lie between the entrant portion 8 of iront part 3 and the central part or band 4., said spaces being provided by forming the part 8 of less size thanpart d and providing ro 'ections 9, which abut the part e and have forme therethrough, Ypref erably tangentially, ports or ducts 10 for deliverin g the motive fluid to the vanes 11 of the turbine wheel 12. transversely ci the wheel 12 at right'angles to the plane thereof, but are dished or curved to better receive the motive fluid issuing from ducts 10. The ducts 10 extend substantially at right angles to the vanes 11-that is, the

lie in the same plane with the turbine-Whse The entire force of the motive fluid is with this arrangement used solely to rotate the turbine-wheel, and no harmful end or side thrust is caused by the motive fluid, as in former constructions.

The turbine-wheel is loosely mounted on a `stub-shaft 18, secured by a screw 14 in the long double b )ss 15 which is formed integral with the solid imperforate wall or web 16 of the part 8.

interposed between the turbine-wheel and the boss 15 is a washer 17.

Loose on the shaft 13 and secured to the turbine-wheel by screws 18 is a cleaner-head 19. A nut 2G, screwed on the end of shaft 13, holds the head 19 and turbine-wheel loosely on the shaft 13.

As long as a motive Huid is sup Y lied to the device the turbine-wheel and c eaner-head will be rotated at high rate, and as the cleaner is pushed through the 4tube or iue by hand the cutters rotate slowl f. The motive iiuid exhausts directly from t e turbinawheel into the tube or flue.

Having thus described my invention, What l claim as new, and desire to secure by Letters Patent, iisl. In a rotary motor or turbine, the com- The vanes 11 extend bination with an inner hollow shell or casing,

of a separate outer hollow shell or casing surrounding the inner shell or casing and sepa- IOC rated therefrom by a motive-Huid space, an

Ionly to the 'space between the said shells or casings,

ducts leading through said hollow inner shell or casin from the motive-Huid space aforesaid 'to tgfle interior `o'f said inner shell or casing said ducts being forwardly inclined and lying substantially in the plane of the turbinewheel, and a rotatably-mounted turbina Wheel having vanes located inside the inner shell or casing, said vanes being positioned to receive the motive fluid issuing from the ducts aforesaid ,in a 'direction substantially at right angles to their surfaces.

2. In a rotary motor or turbine, the comu bination with an inner hollow shell or casing, of a Separate-outer hollow shell or casing surrounding the inner hollow shell or casing and separated therefrom by a plurality of nrotivefluid pockets, an annular member completely closing the outer 'end ofthe motive-fluid space betwe'ensa'iLl/irnienandrou-tereshellso f'f'rreas'wheieby the motive fluid may be 'introduced lonly to the v.space between the said shells or casings, duets leading from the respec- 'tive pockets aforesaid through said hollow inner shell or casing to the interior thereof to let the motive Huid through, saidducts being forwardly inclined and lying substantially in the plane of the turbine-wheel, and va rotatably-mounted turbine-wheel having vanes lo,- cate'd inside the inner shell or casing7 said vanes being positioned to receive the motive fluid issuing from the ducts aforesaid in a direction substantially at 'right angles 'to their surfaces.
